Can someone please advise me on the power reserve of a 1946 Rolex bubbleback?

Some of the bubbleback movements are often noted as having a 41h power reserve. I can't swear that this was an official Rolex specification, but it seems plausible. Of course, you would not necessarily expect an 80 year old watch to have the same performance.
